ABSTRACT:
Methods and apparatus implementing a technique for preparing one or more vector data objects for rendering. In general, in one aspect, the technique includes receiving an object that is a vector data object and defining clipping states of the object. Each clipping state of the object represents an appearance of the object for a region of the object. The technique includes, for each clipping state, determining whether a clipping path is needed to render the appearance of the object represented by the clipping state and generating clipping instructions in accordance with the determining. The technique includes, for each clipping state, generating rendering instructions for rendering the appearance of the region of the object represented by the clipping state. The technique includes associating the generated clipping and rendering instructions to the corresponding clipping states.
